Patent JP-S60207026-A (JP)
Title: Temperature detector
Inventor: USAMI HIROSHI
IPC: G01K11/12
Filed: 1984-03-31
Abstract: PURPOSE:To eliminate the effects of the coupling efficiency of a system and the transmission loss in an optical fiber, by imparting light ouptuts emitted from two sources to a temperature sensor in a time division mode, isolating and extracting the transmitted light beams, and performing comparison and computation. CONSTITUTION:Light sources 11 and 12 emit light alternately in synchronization with the clock signal from a synchronizing circuit 18. The emitted light outputs are inputted to a temperature sensor 3 through a light coupling circuit 13 in a time division mode. The transmitted light from the temperature sensor 3 is converted into an electric signal by a photoelectric converter 5. The signal undergoes time division by a switching circuit 14, which is synchronized with a light- emitting-element driving circuit 10. Photoelectric convertsion signals corresponding to the light sources 11 and 12 are inputted to an operation circuit 17 through smoothing circuits 15 and 16. The operation circuit 17 computes the ratio between both signals and detects the temperature based on the transmittance of the temperature sensor 3.

Title: Signal recording and reproducing device
Inventor: ISHIDA SADANOBU
IPC: H03M13/00
Filed: 1979-05-24
Abstract: PURPOSE: To suppress generation of alien sound dependent upon signal error, by inhibiting the sound analogue signal output when the number of signal errors detected by the cyclic code becomes a prescribed value or more for a prescribed time.  
     CONSTITUTION: In case of error in reproduced data, error detecting circuit 11 dependent upon cyclic code CRC outputs only one pulse during 1 H period and inputs this pulse to AND circuit 18 through retrigger monostable multivibrator I 17. Counter 19 stops counting and resets contents when the output of circuit 18 which appears at the reset input is O, and counter 19 counts the number of rise of output pulses of circuit 11 only when the output of circuit 18 is 1; and when contents reach a prescribed number, counter 19 outputs a downward pulse to the output, and thus, this operation is repeated. Retrigger monostable multivibrator II 20 starts counting from fall of the output pulse of counter 19; and when the output pulse is 0, output inhibiting circuit 21 causes the output of LPF14 to appear at the output terminal of the device; and when the output pulse above is 1, circuit 21 inhibits the output. As a result, generation of alien sound dependent upon signal error can be suppressed.

Title: Formation of fluorescent screen
Inventor: MASAGO KENJI
IPC: H01J9/227
Filed: 1986-03-22
Abstract: PURPOSE:To prevent the deterioration in color purity and avoid a color mixture, by maintaining the exposed portion at a high temperature after exposing a sensitive adhesive spread over a base plate. CONSTITUTION:The exposure is carried out by moving step by step the exposing angle (the radiating angle of the light) at a specific value in stripe forms. In such a process, the sensitive adhesive 2 gets hygroscopic property one by one at the stripe-form exposed portions 2a, 2b..., and when it is allowed in a humid atmosphere, it gets an adhesive property after absorbing moisture. In this case, by humidifying after keeping the base plate 1 in a high temperature atmosphere and heating it there, the temperature of the sensitive adhesive 2 is maintained higher than that of the humidifying atmosphere constantly. Therefore, a spread of the moisture from the exposed portion 2a to unexposed portions is prevented, and the so-called fogging, that the powder of phosphors 3a and 3b are attached to the unexposed portions, in the following fluorescent screen forming process, is avoided. Therefore, the deterioration of color purity or the color mixture of the color CRT are prevented when the fluorescent screen is made in its forming process.

Title: Apparatus for detecting abnormal vibration of machine
Inventor: HIRAMA YUTAKA
IPC: G01H11/02
Filed: 1986-03-25
Abstract: PURPOSE:To make it possible to detect the abnormal vibration of a machine, by constituting a vibration sensor of a magnetic body capable of being attracted to an area suitable for detecting the vibration of the machine and the coil arranged around said magnetic body. CONSTITUTION:At first, one pole of a permanent magnet 10 is attracted to a measuring area and the magnetic piece 9a of a vibration sensor 9 is attracted to the other pole of the permanent magnet 10. By this method, the vibration sensor 9 is fixedly mounted to the measuring area 8 in an attracted state. Next, when a machine is vibrated, this vibration vibrates the magnetic piece 9a from the measuring area 8 through the permanent magnet 10. Because the magnetic piece 9a is magnetized by the permanent magnet 10, voltage is induced in a detection coil 9b corresponding to the change in magnetism due to vibration. Subsequently, induced voltage is inputted to a vibration display part 11 from a terminal 9d to be amplified by an amplifier 12 and a vibration display meter 13 displays deflection according to the amplified voltage. By reading this meter 13, the abnormal vibration of the machine can be detected.

Filed: 1986-03-25
Abstract: PURPOSE:To reduce the loss in a base drive circuit and to plan on shortening the OFF time of a transistor, by fluctuating the base current in proportion to the collector current of a transistor and keeping it in an optimum value. CONSTITUTION:When the collect current of a transistor 5 increaes, ths proportionate voltage is outputted from a current detector 4 and the wattage dissipation of a load ll is reduced. Thus the voltage Vb given from a power circuit 10 to a base drive circuit 8 is increased and the base current Ib of the transistor 5 increased. when the collector current of the transistor 5 decreases, the wattage dissipation of the load ll increases accordingly. Thus the voltage Vb given from the power circuit 10 to the base drive circuit 8 is increased and the base current Ib of the transistor 5 decreased.

IPC: C25D3/56
Filed: 1983-04-13
Abstract: PURPOSE:To obtain a titled electroplated steel plate of which the non-plated surface has excellent chemical convertibility by forming an extra thin plating layer of a Zn-Ni alloy on the opposite side of the steel plate where plating is not required then dissolving preferentially the Zn on the plated layer and subjecting the steel plate to Zn-Ni alloy electroplating on the one side. CONSTITUTION:A Zn-Zi alloy contg., for example, about 13% Ni content is plated on a steel strip at a prescribed coating weight by using a sulfuric acid bath kept at 1.8pH and 55 deg.C and thereafter the strip is dipped in the plating bath without conducting electricity thereto. An extrathin plating layer of the Zn-Ni alloy is also formed on the opposite side where plating is not required, then the strip is passed through the succeeding bath. The Zn on the side requiring no plating is preferentially dissolved during the passage and an Ni-rich layer having finally 30-2,000mg/m<2> coating weight is formed thereon upon completion of the passage. As a result, the contamination during the plating treatment of the non-plated surface is prevented and the one side Nn-Ni alloy electroplated steel plate having improved chemical convertibility is obtd.

Abstract: PURPOSE:To prevent dew condensation at an optical system which projects an original image on a photosensitive surface without using any heater by flowing air outside of the luminous flux incidence port and projection port of a box- shaped structure which shields the optical system from external air substantially. CONSTITUTION:The 1st mirror 4, a zoom lens 3, and the 2nd mirror 5 are arranged in the box-shaped structure 39; the incidence port 34 for luminous flux from an original O is blocked with the 1st dust-protective transparent glass 41 and the projection port 10 for luminous flux from the optical system is blocked with the 2nd dust-protective transparent glass 40 to form the substantially sealed structure. The inside, therefore, varies in temperature and humidity gradually against abrupt variation in temperature and humidity and dew condensation never occurs. Further, strong air is blown to an platen 1 and the 1st dust-protective glass 41 by a suction fan 31, so dew condensation hardly occurs. The air flows on the surface of the 2nd dust-protective glass 40 and is warmed slightly by the radiation plate 46 of a power transformer 45 and a circuit board 44, so dew vaporizes speedily even if condensed.
